Energy Self-Sufficiency through Geothermal Energy and Solar Power

Energy is the most important “raw material” of our time. At the same time, it represents a significant cost factor in the balance sheet of most companies. So we take advantage of every opportunity to reduce the amount of energy we purchase. One example is the construction of a new office building at our company's main location in Hamburg.

A common feature of companies that are expanding is the need to physically extend existing facilities or open new ones, both of which require construction measures. In keeping with the general request of Hamburg's economic authority (Hamburger Wirtschaftsbehörde) to work actively to reduce CO2 emissions in the Hamburg area, our construction measures offer us the opportunity to improve our ecological footprint.

A good example is the new office building at our company's main location in Hamburg. In 2013, we evaluated, planned and implemented the utilization of the site's existing geothermal energy for heating and cooling the entire building, and since 2014, the heat pumps required by the geothermic plant are no longer supplied with external electrical power, but with solar power generated by the system on the roof of that new building through the day. Although it is occasionally necessary to use externally sourced electrical power at night, the new building has a nearly even energy balance.

Eppendorf's extensive test drilling and the insights it gained from the use of different types of probes and drilling depths were pioneering efforts in the region. We were well aware of the uncertainties of such a project, but it was a challenge we enjoyed meeting, and our efforts were rewarded by the energy self-sufficiency of the building, the valuable insights we gained into the use of geothermic systems in the region, and the concrete contribution the project enabled us to make to the goal of an environmentally friendly energy supply.
